Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33485988, here are decompositions:

31 + 33485957 = 33485988
47 + 33485941 = 33485988
79 + 33485909 = 33485988
97 + 33485891 = 33485988
101 + 33485887 = 33485988
149 + 33485839 = 33485988
157 + 33485831 = 33485988
167 + 33485821 = 33485988

Showing the first eight; more decompositions exist.
